Question

How do you find the equation of the circle given center:(0,0) radius: 2 square root of 7?

Answer 1

Answer:

x² + y² = 28

Step-by-step explanation:

C (0.0)

r = 2√7

Equation of circle = (x - h)² + (y - k)² = r²

where (h,k) is the center and r is the radius

Equation of the given circle = (x - 0)² + (y - 0)² = (2√7)²

                                              = x² + y² = 28

Hope this helps! :)
